    Hi all.
    One of the configurations I am exploring is putting an electric Motor in the LAR keels with the shaft coming out the back. My question relates to the hydrodynamics of having a prop directly behind a LAR keel. The dimensions of the LAR is 4.5meters by 400 mm deep by 302mm max wide. Typical aero foil shape.
    Any comments re the position of the propeller. No electric motor v diesel questions...just hydrodynamics and prop efficiency effects.
    Regards
    Mick
